PHP table to Excel file - php

Question

I can't figure out how to export a php table to an existing Excel file.
I'm new in php and until now I didn't understand how can I do that.
From my search I saw that it's needed a while and foreach statement.
<?php
$sql_data = date('d.m.Y', strtotime('-1days'));
require(realpath(dirname(__FILE__)."/PHPExcel-1.8/Classes/PHPExcel.php"));
$conn = oci_connect('USER', 'PASS', 'dark:1521/DAR');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
Else {echo 'Connection successfully !';
}
$parametri = oci_parse($conn, "SELECT * FROM TABLE_1 WHERE TO_DATE('${sql_data}','DD.MM.YYYY') BETWEEN T_FROM AND T_TILL");
oci_execute($parametri);
echo "<table border='1'>\n";
while ($row = oci_fetch_array($parametri, OCI_ASSOC+OCI_RETURN_NULLS)) {
echo "<tr>\n";
foreach ($row as $item) {
echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>\n";
}
echo "</tr>\n";
}
echo "</table>\n";
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue('A1', 'UD_NAME');
$objPHPExcel->getActiveSheet()->SetCellValue('B1', 'UD_CODE');
$objPHPExcel->getActiveSheet()->SetCellValue('C1', 'TECH_TYPE');
$objPHPExcel->getActiveSheet()->SetCellValue('D1', 'PPE_NAME');
$H_col = $objPHPExcel -> setActiveSheetIndex(0)->getHighestColumn();
$nr_col = PHPExcel_Cell::columnIndexFromString($H_col);
$nr_row = $objPHPExcel -> setActiveSheetIndex(0)->getHighestRow();
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->save(str_replace('.php', '.xlsx', __FILE__));
?>

function saveExcelFile($objPHPExcel, $file){
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: ' . $file . ';filename="01simple.xls"');
header('Cache-Control: max-age=0');
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;
}
try this instead of
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->save(str_replace('.php', '.xlsx', __FILE__));
try to run phpexcel, "header was sent error" you can't use "echo" before headers
require(realpath(dirname(__FILE__)."/PHPExcel-1.8/Classes/PHPExcel.php"));
function saveExcelFile($objPHPExcel, $file){
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: ' . $file . ';filename="01simple.xls"');
header('Cache-Control: max-age=0');
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: '.gmdate('D, d M Y H:i:s').' GMT'); // always modified
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0
$objWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;
}
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$objWorksheet = $objPHPExcel->getActiveSheet();
$objWorksheet->SetCellValue('A1', 'UD_NAME');
$objWorksheet->SetCellValue('B1', 'UD_CODE');
$objWorksheet->SetCellValue('C1', 'TECH_TYPE');
$objWorksheet->SetCellValue('D1', 'PPE_NAME');
saveExcelFile($objPHPExcel, 'attachment');
i don't know how this code below works, but test it separate
$sql_data = date('d.m.Y', strtotime('-1days'));
$conn = oci_connect('USER', 'PASS', 'dark:1521/DAR');
if (!$conn) {
$e = oci_error();
trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
}
Else {echo 'Connection successfully !';
}
$parametri = oci_parse($conn, "SELECT * FROM TABLE_1 WHERE TO_DATE('${sql_data}','DD.MM.YYYY') BETWEEN T_FROM AND T_TILL"
oci_execute($parametri);
echo "<table border='1'>\n";
while ($row = oci_fetch_array($parametri, OCI_ASSOC+OCI_RETURN_NULLS)) {
echo "<tr>\n";
foreach ($row as $item) {
echo " <td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : " ") . "</td>\n";
}
echo "</tr>\n";
}
echo "</table>\n";
